Once you have a case, try to find at least two different sources that detail the same case. This can be a report from a newspaper, an article about fingerprints that references the case, or an excerpt from a textbook or academic report that discusses the case. Be sure to keep track of the resources you use in your research and include them in a brief ‘Works Cited’ list at the end of your report.
In one paragraph each:

1. Provide the details of the case.

2. Explain exactly the role that fingerprint evidence played in solving the crime.

Ithink the answer would be a

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
